Attempt to remove linker workaround on the buildbots: Attempt 2

The first commit removed the workaround in a old script.
This patch removes it in the file actually used by the bots.

I have no idea if this is still needed, but removing the
workaround seems like the easiest way to test.

I'll revert this change if the bots go red.
